Spunk,
Lets look at this further, consider this...guys applying mono by hand will have the gear much more rounder than machine guys.Bearing this in mind, We have sprayed monos, and on the same job, applied some akward areas by hand and after a good period of drying the tones of the different areas have been un distinguishable. Are we to concider that the pigment remains inconsistent with even the most slightest of water variations.I beleive that through colour systems must be manufacturered with a certain degree of tolerance in mind,to accomodate instances as you point out.
